What affects solubility
Temperature - the experiment where heated the water in
a test tube and _ copper sulfate showed us that we could
keep copper sulfate while the temperature of the water was .
Surface area � If we increase the surface of the solute by crushing it
it will faster.
Concentration.
If we have lots of _ solute in a solution its called concentrated. If there not much its dilute.
Suspensions
When a _ does not dissolves but floats in the solvent its a suspension. Eventually it will settle to the bottom the flask. Then its called a sediment.
Colloids
Are tiny insoluble particles that never settle as sediment. are paint,

Separating techniques
You can separate solids mixtures by using a range of techniques. To do _ separating you need to know the properties of the in the mixture. Choose a property that is different any others in the mixture and then choose a _ that will allow you to separate the solids

Separating sand and iron filings
The of these are
Properties of sand

of iron filings
Does not dissolve in water

So to separate these 2 we will _ irons magnetic properties because sand is not magnetic.
_ of how you did this.
Using a centrifuge separate substances
Substances with a greater mass will out of solution that is spun at high speed the lighter particles will settle. This method is used separate red blood cells out of blood plasma.
_ this muddy water in a bucket and spin it _- what happens?
Draw a picture.
Separating solutions _ n a mixture
Chromatography.
This can used to separate the colour inks in a pen. works because the different colours have a different weight. _ lightest ones travel the furthest up the filter paper.
Paste in results.
Distillation
This will separate different _ if they have a different boiling point. Eg separating _, from water. Copy the picture (fig 3.3.2) on page of the text
The distillation apparatus works because water boils at _ degrees C. The liquid water is heated so it _ state from a liquid to a gas. The water _ is passed along a cooling tube � called the _. The condensor is a glass tube inside a glass . This forms a sleeve. Cold water is passed around _ sleeve. In the condenser the water changes state back a liquid. This liquid is now collected in a _.
Collecting water in the .
We a bush still by collecting leaves and putting it a closed container. We hope the water will evaporate _ of the leaves and become a gas. The gas cool down on the underside of the plastic and _ should run into our collecting jar.

Absorption
Absorption is a separating _ that relies on one of the substances being able be absorbed into something like a sponge or kitchen _.
When _ buy meat the packaging some times has a small like pad that sits below the meat to separate _ meat from meat juice and blood. It does this soaking up the blood.
